Application August 20,

3 Claims.

The invention relates to cage construction and more especially to bird cages.

The primary object of the invention is the provision of a cage of this character, wherein the crown of its body carries a removable cap or head piece which is separable from without the body, so that access may be had to the interior of the body at the top thereof.

Another object of the invention is the provision of a cage of this character, wherein the removable cap or head piece carries a swinging perch which is readily extractible through the open top of the cage body and in this manner the former, as well as the perch can be conveniently and more thoroughly cleaned to have the cage sanitary.

A further object of the invention is the provision of a cage of this character, wherein the cap or head piece in its removable fitting with the 20 body of the said cage has associated therewith a gasket or washer of the resilient kind and such cap or head piece is releasably latched in position, being releasable from without the body of the cage.

A still further object of the invention is the provision of a cage of this character, which is extremely simple in construction, thoroughly reliable and eflicient in operation, strong, durable, easily cleaned, and inexpensive to manufacture.

With these and other objects in view the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawing, which discloses the preferred embodiment of the invention, and pointed out in the claims hereunto appended.

In the accompanying drawing:

Figure 1 is a vertical sectional view through a bird cage constructed in accordance with the invention.

Figure 2 is a fragmentary plan view looking toward the inner face of the crown portion with the cap or headpiece removed.

Figure 3 is an inner face view of the cap or headpiece removed from the body of the cage.

Similar reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing in detail A designates generally .a portion of a bird cage which involves as usual a base or bottom plan an, in this instance of circular shape, although it may be of any other shape, being preferably made from sheet metal stamped or otherwise dished.

In association with the base or bottom pan [0,

as is usual, is the body II, in this instance being a wire frame having an arched or convex shaped crown portion [2. This arched or convex shaped crown portion at its center carries a keeper ring I3 forming an opening [4 in said portion.

The keeper ring i3 is provided in its inner periphery with diametrically opposed notches IS, the opening l4 being of the desired size for a purpose presently described.

Covering the opening I4 is a removable cap or head-piece I6 overlapping for a distance the crown portion l2 and at the inner side of said cap or head-piece I6 is an inverted substantially T-shaped latch I! which is passed through the notches I5 .and on the turning of the cap or headpiece It frictionally locks with the keeper ring I3, and in this manner the cap or head-piece is separably fastened in place on the body II at the crown portion l2 thereof for the closing of the opening I I in the latter.

The ring I3 serves as a seat for a gasket or sealing washer I8 made from cork, rubber or a composition of materials which closes the joint between the said ring and cap or head-piece.

Centrally fitted in the cap or head-piece I6 is a hanger 19 formed with an eye 20 without the cap or headpiece, while suspending within the body II a swing perch 2| which freely passes through the opening l4 and notches l5, respectively, when the cap or head-piece is detached, so that said perch 2| and the latter can be readily and conveniently cleaned. The eye 20 is for the hanging of the cage or the carrying of the same in the hand.

From the foregoing it is thought that the construction and manner of operation of the inven-- tion will be clearly understood and therefore a more extended explanation has been omitted. It is to be understood that changes, variations and modifications may be made in the invention as fall properly within the scope of the appended claims, without departing from the spirit of the invention or sacrificing any of its advantages.

What is claimed is:

1. A cage having a top, an opening in said top and a perch holder and perch secured to said top at said opening; said opening having slots extending therefrom in opposite directions forming an opening of greater dimension than the first named opening whereby a perch having a length greater than the first named opening and less than the second opening may pass through the opening and be removed from the cage.

2. The combination of a cage for flying birds, the case having a top, the top having a central opening surrounded by a ring, a cap larger than the opening and having a depending generally cylindrical member capable of extending through the ring, and a perch supported by the cap, capable of passing through the ring and depending within the cage when the cap is on the cage, said ring and said cylindrical member having interlocking structure which when interlocked prevents vertical movement of the cage relative to the cap and perch, and which in another position permits the cap and perch to be removed as a unit from the cage, whereby the perch may be inserted and removed by a person without insertslots when the closure is moved through the ring, 10

during removal of the cap from the cage.
